01 - In a mixing bowl, whisk together the buttermilk, salt, pepper, garlic powder, and paprika until well combined. Add the chicken strips, ensuring each piece is thoroughly coated. Allow to marinate for at least 10 minutes, or up to 2 hours in the refrigerator for deeper flavor penetration.
02 - In a separate shallow bowl or dish, combine the panko breadcrumbs, all-purpose flour, paprika, onion powder, cayenne pepper (if using), and salt. Mix evenly so the seasonings are distributed throughout the breading.
03 - Preheat the air fryer to 400°F for 3 minutes to ensure the cooking chamber is at the proper temperature for optimal crisping.
04 - Remove each chicken strip from the marinade, allowing the excess buttermilk to drip off. Dredge each piece in the breadcrumb mixture, pressing lightly on all sides to ensure the coating adheres firmly.
05 - Place the breaded tenders in a single layer inside the air fryer basket, leaving space between each piece for proper air circulation. Spritz the tops lightly with olive oil spray to promote even browning.
06 - Cook at 400°F for 10 to 12 minutes, flipping the tenders halfway through the cooking time. The chicken is done when the exterior is golden brown and crispy, and the internal temperature registers 165°F on a meat thermometer.
07 - Transfer the tenders to a serving platter and serve immediately while hot. Pair with your preferred dipping sauces such as honey mustard, ranch, or barbecue sauce.
